Specification of Letters Patent.

Application filed October 26-, 1911. Serial No. 656,797.

To all whom it may concern.

Be 1t known that I, ADoLF ALFRED SCHNEIDER, a citizen of the German Empire,

residing at Dresden-1L, in the Kingdom of Saxony andrEmpire of Germany, have invented certain new and useful Improve ments in Chocolate-Holding Apparatus, of which the following is a specification.

It is well known that the band of chocolate-paste which is delivered by the nozzle from the filling-receptacle of a chocolatemolding apparatus in a predetermined quan tity, does not become detached from the nozzle, especially when the chocolate-paste is tough and of considerable consistency. When the molds or other vessels are conducted past the nozzle during the period of the delivery of the paste, the serious 0bjection is found that some of the paste which is delivered after the mold has passed below thenozzle, is dropped over the rear-edge of the mold or other vessel and retained on the same and partly dropped on the conveyer-belt of the mold, so that a considerable portion of the paste is lost. To overcome this objection, mechanical devices for separating or cutting off the paste from the nozzle have been proposed. But, owing to the fact that a cut-off device requires a special mechanism which has to be actuated at a certain moment, namely: at the moment when the rear edge of the mold or other vessel which is passing below the nozzle, arrives immediately under the mouth of the delivery-nozzle.

The object of this invention is to overcome the objection referred to in an entirely different manner, namely by moving the mold or other vessel for the reception of the chocolate-paste in one direction below the nozzle and then, as soon as the rearedge of the mold arrives below the nozzle, in a reverse direction so that thereby the end of the paste is broken off at the nozzle and dropped into the mold. In this manner not the slightest quantity of paste is lost and all the paste used up without requiring any mechanical cut-ofi device, by the simple reversal of the motion of the mold, by which i the reliable detaching of the paste from the nozzle and the delivery of the free end into the mold is obtained.

In the accompanying drawing, Figures 1 and 2 represent a side-elevation of my improved filling device for chocolate-molds .by the arrow shown in Fig. 1.

which shows the two stages of my improved process of filling chocolate-molds. Similar letters of reference indicate cor- Patented Oct. 5, 1915.

responding parts throughout the figures of paste is delivered by a nozzle (0 into the mold Z) by forcing a predetermined quantity of the paste through the nozzle 64 into the mold. 1

Z). The mold Z) is placed on an endless conveyer-belt 0 which is moved in one direction below the opening of the nozzle, as indicated The conveyer-belt c is moved in such a manner that the mold passes under the nozzle while the quantity of the paste is pressed through the nozzle. As soon as the rear-edge d of the mold arrives below the nozzle, the forward motion of the belt is interrupted and a reverse motion in the 0 pposite direction imparted to the .same.

backward for breaking off the band of paste, and then forward again. The filled mold is then removed and the evening up of the paste in the mold is then accomplished in. the usual manner on a so-called beating table.

The mechanical means by which the alternating forward and reverse motion is imparted to the mold can be of any approved construction. The mechanism shown in the drawing consists of a lever e which is applied to a shaft 2' to which rotary-reciproeating motion is imparted. The lever e carries a pawl g which engages a ratchetwheel 7 for moving the conveyer in one direction, while the reverse motion is accomplished by a second pawl g onthe opposite side of the lever engaging the teeth of a second ratchet-wheel h, after which a forward motion is again imparted to the con.- veyer-belt, a new mold placed on the feedend of the belt and the filled mold removed always in free and full communication with said filling receptacle, whereby a continuous stream of material always enters from said filling receptacle into said nozzle, said nozzle being stationary, a conveyer-belt passing underneath the outlet of said nozzle, and adapted to carry molds for the paste delivered from the mouth of said nozzle, said nozzle and the mouth thereof being always open, whereby a continuous stream passes through said nozzle and out of the mouth thereof, means for moving said conveyerbelt in a given direction so as to carry said mold from one end thereof to the other under said nozzle, to receive the material flowing from the mouth of said nozzle, and means for suddenly reversing the motion of said conveyer-belt as the posterior end of said mold passes directly underneath the said mouth of the said nozzle, so that the said stream of material passing continuously from said filling receptacle and through said nozzle is broken ofi, the severed end of said stream falling into said mold.

2. In a chocolate-molding apparatus, a filling receptacle, a nozzle, said nozzle being always in free and full communication with said filling receptacle, whereby a continuous stream of material always enters from said filling receptacle into said nozzle, said nozzle being stationary, a conveyer-belt passing underneath the outlet of said nozzle, and adapted to carry molds for the paste deliver-ed from the mouth of said nozzle, said nozzle and the mouth thereof being always open, whereby a continuous stream passes through said nozzle and out of the mouth thereof, means for moving said conveyerbelt in a given direction so as to carry said mold from one end thereof to the other under said nozzle, to receive the material flowing from the mouth of said nozzle, and means for suddenly reversing the motion of said conveyer-belt as the posterior end of said mold passes directly underneath the said mouth of the said nozzle, so that the said stream of material passing continuously from said filling receptacle and through said nozzle is broken off, the severed end of said stream falling into said mold, said mold being spaced from the mouth of said nozzle.

In testimony, that I claim the foregoing as my invention, 1 have signed my name in presence of two subscribing witnesses.
